Abstract

Abstract

The beam profile measurement of BEPCⅡ storage ring by visible synchrotron light imaging method is illustrated. The optics details and precise measurement of the magnification by the method are elaborated. Approaches for possible arbitrary error and system errors are suggested, such as dealing with the diffraction error by using point spread function (PSF) deconvolution, which are also available for other similar measurement like X-ray pinhole camera. The measurement results agree well with the spatial interferometer method data.
